Description
本新型涉及一種醫療的器械，尤其涉及一種用於植入骨骼手術的縫合錨釘與其系統。 The model relates to a medical instrument, in particular to a suture anchor used for bone implantation surgery and its system.
錨釘是應用於縫合韌帶等軟組織的手術器械，使用於縫合手術時是先利用錨釘將縫線的一端固定於骨骼上，以縫線縫合軟組織後，接著再使用另一錨釘將縫線另一端拉緊、固定。為了將錨釘植入骨骼中，目前的作法是以器械在骨骼鑿出導孔，接著再以驅動桿穿入錨釘，轉動驅動桿來帶動錨釘由導孔鎖入骨骼內。然而，上述的現有的做法存在一些問題。 An anchor is a surgical instrument used to suture ligaments and other soft tissues. When used in suture operations, one end of the suture is fixed to the bone with an anchor, and the soft tissue is sutured with the suture, and then another anchor is used to connect the suture. The other end is tightened and fixed. In order to implant the anchor into the bone, the current practice is to drill a guide hole in the bone with an instrument, and then use a driving rod to penetrate the anchor, and then rotate the driving rod to drive the anchor to lock into the bone through the guide hole. However, the above-mentioned existing approach has some problems.
首先，現有的錨釘一般周圍的螺牙是三角形的螺牙，因此錨釘利用螺牙鎖入骨骼內時，接觸骨骼的面積較小因此螺鎖後的結構較不穩固，無法更緊密地結合骨骼內。再者，由於錨釘是以螺鎖於導孔的方式固定，故於螺鎖錨釘前需要預先在骨骼鑿出較大的導孔，此對骨骼周邊組織的破壞程度較大，不利於手術後癒合，且錨釘的牢固性亦較差，替換鑿孔與驅動桿等器械的步驟亦使得手術變得更加繁瑣又耗時。 First of all, the existing anchors usually have triangular screws around them. Therefore, when the anchors are locked into the bones with the screws, the area of contact with the bones is small, so the screwed structure is less stable and cannot be tightly combined. Within the bones. Furthermore, because the anchor is fixed by screwing to the guide hole, it is necessary to drill a larger guide hole in the bone before screwing the anchor, which will damage the surrounding tissues of the bone to a greater extent, which is not conducive to surgery. Post-healing, and the anchor's firmness is also poor, the steps of replacing the gouge and driving rod and other instruments also make the operation more cumbersome and time-consuming.
由於現有的錨釘固定於骨骼會有結構較不穩固，以及預先在骨骼鑿出的導孔較大容易破壞骨骼周邊組織造成癒合狀況不佳的缺點。為此，本新型藉由錨釘周圍螺牙形成較大接觸面積的設計，以及螺牙於前端形成入牙口的設計，達到錨釘螺鎖於骨骼穩固以及鎖入時破壞骨骼周邊組織較少的功效。 Because the existing anchors are fixed to the bones, the structure is less stable, and the guide holes drilled in the bones in advance are large and easily damage the surrounding tissues of the bones, resulting in poor healing. For this reason, the new model uses the design of the screw teeth around the anchor to form a larger contact area and the design of the screw teeth to form the entrance port at the front end, which achieves the effect of anchoring the anchor screw to the bone stably and less damaging the surrounding tissues of the bone when locked in. .
為達到前述創作目的，本新型提供一種縫合錨釘，設有一錨釘本體，是直管狀並具有前、後兩端，於該錨釘本體的軸心沿軸向貫穿一非圓形的旋刃插孔，於該錨釘本體的後端部形成一穿線構造，於該錨釘本體的外周面形成一沿螺鎖方向由後向前螺旋延伸的螺牙構造，該螺牙構造前端螺旋的幅度收窄並於該錨釘本體的前端面形成一入牙口，該螺牙構造的截斷面為梯形並且兩側之間的夾角為45至55度，該螺牙構造的截斷面頂端定義為一牙山，該牙山的寬度為0.4至0.7mm。 In order to achieve the foregoing creative purpose, the present invention provides a suture anchor with an anchor body, which is straight and has front and rear ends, and a non-circular spiral blade penetrates through the axis of the anchor body in the axial direction. The insertion hole is formed with a threading structure at the rear end of the anchor body, and a thread structure spirally extending from back to front along the screw locking direction is formed on the outer peripheral surface of the anchor body. The spiral width of the front end of the thread structure is Narrowing and forming an entry port on the front end surface of the anchor body, the cross-sectional surface of the screw structure is trapezoidal and the angle between the two sides is 45 to 55 degrees, and the top of the cross-sectional surface of the screw structure is defined as a tooth Mountain, the width of the Asan is 0.4 to 0.7mm.
較佳的，本新型該螺牙構造的高為0.6至0.9mm，該螺牙構造的截斷面底端定義為一牙底，該牙底的寬度為1.1至1.3mm，該牙山與該牙底寬度尺寸的比值為0.5。或者，較佳的，本新型該螺牙構造截斷面兩側之間的夾角為50度，該螺牙構造的高為0.7mm，該牙山的寬度為0.6mm，該牙底的寬度為1.2mm。 Preferably, the height of the thread structure of the present invention is 0.6 to 0.9mm, the bottom end of the cut surface of the thread structure is defined as a tooth bottom, and the width of the tooth bottom is 1.1 to 1.3 mm. The ratio of the bottom width dimension is 0.5. Or, preferably, the included angle between the two sides of the cut-off surface of the thread structure of the present invention is 50 degrees, the height of the thread structure is 0.7mm, the width of the tooth mountain is 0.6mm, and the width of the tooth bottom is 1.2 mm.
進一步，本新型該旋刃插孔是以該錨釘本體的軸心為中心的多邊形孔，該旋刃插孔於該錨釘本體前端面的周圍形成三個以上位於同一圓形軌跡的刃角，該入牙口位於沿該螺鎖方向落後其中一刃角10至15度的位置，如此使該入牙口於旋轉時緊跟於該刃角的後方。 Further, the rotary blade insertion hole of the present invention is a polygonal hole centered on the axis of the anchor body, and the rotary blade insertion hole forms more than three blade angles located on the same circular track around the front end surface of the anchor body The tooth entrance is located 10 to 15 degrees behind one of the blade angles along the screw locking direction, so that the tooth entrance is closely behind the blade angle when rotating.
為達到前述創作目的，本新型亦提供一種縫合錨釘系統，可供固定於一骨骼上，該縫合錨釘系統包括一前述的縫合錨釘以及一旋刃，其中：該旋刃是截斷面形狀配合該旋刃插孔的桿體，於該旋刃的前端形成一尖端部，該旋刃 穿置於該縫合錨釘的該旋刃插孔使該尖端部向前穿出該旋刃插孔，當該旋刃旋轉時可驅動該縫合錨釘，使該縫合錨體藉由該螺牙構造螺鎖入該骨骼。 In order to achieve the aforementioned creative purpose, the present invention also provides a suture anchor system that can be fixed on a bone. The suture anchor system includes the aforementioned suture anchor and a rotating blade, wherein: the rotating blade has a cross-sectional shape To match the rod body of the rotary blade insertion hole, a tip portion is formed at the front end of the rotary blade, and the rotary blade Passing through the spiral blade insertion hole of the suture anchor makes the tip part pass forward out of the spiral blade insertion hole. When the spiral blade rotates, the suture anchor can be driven so that the suture anchor body can pass through the screw thread. The structure is screwed into the bone.
較佳的，本新型該旋刃的長度為該縫合錨釘的兩倍，該旋刃的後半部穿設於該縫合錨釘的該旋刃插孔並且前半部向前穿出該旋刃插孔。 Preferably, the length of the rotating blade of the present invention is twice that of the suture anchor, the back half of the rotating blade penetrates the rotating blade insertion hole of the suture anchor, and the front half penetrates forward from the rotating blade insert. hole.
進一步，本新型該旋刃插孔是以該錨釘本體的軸心為中心的多邊形孔，該旋刃插孔於該錨釘本體前端面的周圍形成三個以上位於同一圓形軌跡的刃角，該入牙口位於沿該螺鎖方向落後其中一刃角10至15度的位置，如此使該入牙口於旋轉時緊跟於該刃角的後方。 Further, the rotary blade insertion hole of the present invention is a polygonal hole centered on the axis of the anchor body, and the rotary blade insertion hole forms more than three blade angles located on the same circular track around the front end surface of the anchor body The tooth entrance is located 10 to 15 degrees behind one of the blade angles along the screw locking direction, so that the tooth entrance is closely behind the blade angle when rotating.
當本新型前述的縫合錨釘或縫合錨釘系統使用時，是將配合旋刃插孔的旋刃穿過該縫合錨釘的旋刃插孔，由於縫合錨釘的旋刃插孔是非圓形，使得配合縫合錨釘的旋刃的截斷面也是非圓形，在旋刃的周圍形成數個外凸的刀刃。 When the aforementioned suture anchor or suture anchor system of the present invention is used, the rotary blade that matches the rotary blade insertion hole is passed through the rotary blade insertion hole of the suture anchor, because the rotary blade insertion hole of the suture anchor is non-circular , So that the cross-sectional surface of the rotating blade matching the suture anchor is also non-circular, and several convex blades are formed around the rotating blade.
如此，當旋刃旋轉時不僅可用於帶動縫合錨釘旋轉，且旋刃外凸的刀刃在旋轉後能夠擴大銑削的半徑，在骨骼上形成足以供螺牙構造螺鎖鎖入的導孔，讓螺牙構造能從前端的入牙口陸續鎖入該旋刃前導形成的導孔，並使錨釘本體的整體體積能夠藉由旋刃插孔的縮小而設計為較小的體積，除了讓施術醫師能在一次的操作中將縫合錨釘旋入骨骼，省卻更換器械鑿孔與鑽入錨釘的麻煩以外，也能夠減少在骨骼設置縫合錨釘所需要破壞的骨骼周邊組織，有益於後續組織傷口的癒合。 In this way, when the rotating blade rotates, it can not only be used to drive the suture anchor to rotate, but the convex blade of the rotating blade can expand the milling radius after rotating, and form a guide hole in the bone enough for the screw structure to lock in. The thread structure can be successively locked into the guide hole formed by the screw blade from the front end of the tooth, and the overall volume of the anchor body can be designed to a smaller volume by reducing the screw blade socket, in addition to allowing the surgeon The suture anchor can be screwed into the bone in one operation, which saves the trouble of replacing the instrument to gouge and drilling the anchor. It can also reduce the bone surrounding tissue that needs to be destroyed when setting the suture anchor in the bone, which is beneficial to subsequent tissue wounds. Of healing.
此外，由於本新型於錨釘本體周圍形成的螺牙構造相較於三角形螺牙，是兩側夾角以及牙山寬度較寬的設計，如此使螺牙構造更趨近於方形齒的結構，如此在縫合錨釘螺鎖攻入骨骼時，能以較大面積的螺牙接觸、咬合於骨骼， 能夠獲得螺鎖結合更為穩固的構造，再以後端部的穿線構造用於繫綁或穿線絞合於螺牙構造與骨骼之間的方式固定手術的縫合線。 In addition, since the screw structure formed around the anchor body of the present invention has a wider angle between both sides and the width of the tooth, compared to the triangular screw, the screw structure is closer to the structure of a square tooth. When the suture anchor screw is penetrated into the bone, it can contact and bite with the bone with a larger area of screw teeth. A more stable screw-locked structure can be obtained, and then the threading structure at the rear end is used to tie or thread the thread and twist between the screw structure and the bone to fix the suture of the operation.
在其他的操作使用方式中，本新型亦可僅以旋刃於骨骼鑿出最小需求的鑿孔後，向後至少抽回該旋刃向前穿出該縫合錨釘除尖端部以外的部分，接著旋轉該旋刃帶動該縫合錨釘一同旋轉，使該縫合錨釘以其螺牙構造攻入該鑿孔，最後由該縫合錨釘完全抽出該旋刃，完成該縫合錨釘的植入。如此的操作植入方式能夠最小限度地破壞骨骼周邊的組織，並進一步使螺牙構造攻入鑿孔時需要自行挖開鑿孔周圍的骨骼部分更多，令縫合錨釘植入骨骼後的固定構造更為緊密穩固。 In other modes of operation and use, the present invention can also only use the rotating blade to gouge the bone with the minimum requirement, and then withdraw the rotating blade backwards at least to pass through the suture anchor except for the tip part, and then Rotating the rotary blade drives the suture anchor to rotate together, so that the suture anchor penetrates into the gouge hole with its thread structure, and finally the rotary blade is completely extracted by the suture anchor to complete the implantation of the suture anchor. Such an operation and implantation method can minimize the damage to the surrounding tissues of the bones, and further make the screw structure penetrate into the gouge hole by digging the bone around the hole more, so that the suture anchor is implanted into the fixed structure of the bone. Closer and more stable.

如圖1至圖5所示的較佳實施例，本新型提供一種縫合錨釘系統，包括一縫合錨釘10以及一旋刃20，其中：
As shown in the preferred embodiment shown in Figs. 1 to 5, the present invention provides a suture anchor system, which includes a
該縫合錨釘10設有一錨釘本體11，該錨釘本體11是直管狀並具有前、後兩端，於該錨釘本體11的軸心位置沿軸向貫穿一非圓形的旋刃插孔12，在本較佳實施例中該旋刃插孔12是以該錨釘本體11的軸心為中心的正方形孔，該旋刃插孔12於該錨釘本體11前端面的周圍形成四個位於同一假想的圓形軌跡A的刃角121，該圓形軌跡A也以該錨釘本體11的軸心為中心，於該錨釘本體11的後端部形成一圓柱狀且直徑大於前側的穿線部13，該旋刃插孔12的後端向後貫穿該穿線部13的中央，於該穿線部13形成一穿線構造14，該穿線構造14是在該穿線部13後端面相反兩側各向前穿設一對穿線孔141，配合各對穿線孔141於該穿線部13的外周面形成一U形凹槽142，各U形凹槽142的兩端與各對穿線孔141的內端相通。
The
於該錨釘本體11的外周面形成一沿螺鎖方向由後向前螺旋延伸的螺牙構造15，在本較佳實施例中該螺鎖方向是順時鐘的方向，該螺牙構造15前端螺旋的幅度被削尖收窄，藉此於該錨釘本體11的前端面形成一入牙口151，該入牙口151的位置位於以該錨釘本體11的軸心為中心，沿該螺鎖方向落後其中一刃角121旋轉幅度θ1角度的位置，在本較佳實施例中該旋轉幅度θ1的角度為13度，如此使該入牙口151沿該螺鎖方向旋轉時能緊跟於該刃角121的後方；該螺牙構造15的截斷面為梯形並且兩側之間的夾角θ2為50度，該螺牙構造15的截斷面頂端與底端分別定義為一牙山152以及一牙底153，在本較佳實施例中該牙山152
的表面是相較於該錨釘本體11軸心方向的傾斜角θ3為2至4度的傾斜面，較佳的該傾斜角θ3為3度，該螺牙構造15截斷面垂直於該錨釘本體11軸心方向的高度H1為0.7mm，該牙山152沿該錨釘本體11軸心方向的寬度H2為0.6mm，該牙底沿該錨釘本體11軸心方向的寬度H3為1.2mm，該牙山152與該牙底153寬度尺寸的比值為0.5。
A
該旋刃20是截斷面形狀配合該旋刃插孔的桿體，如本較佳實施例該旋刃20是正方形的桿體，於該旋刃20的前端形成一尖端部21，該尖端部21是中央向前凸出形成尖端的正方形錐體，於該旋刃20周圍的四個轉角處分別形成一刀刃22，在本較佳實施例中該旋刃20的長度略長於該錨釘本體11的長度，使得該旋刃20穿置於該縫合錨釘10的旋刃插孔12時，該旋刃20周圍四個刀刃22的前端部分與該尖端部21會向前穿出該旋刃插孔12，該旋刃20藉由非圓形的截斷面穿置於該縫合錨釘10的非圓形且形狀符合的旋刃插孔12內，使得旋轉該旋刃20時可一併驅動該縫合錨釘10旋轉。
The
本新型除前述較佳實施例，是將該旋刃插孔12以及該旋刃20設為正方形配合的形狀以外，也可將非圓形的形狀設為星形、三角形、五邊形或六邊形等其他多邊形的形狀，這時該旋刃20的尖端部21的錐狀以及各刀刃22的數量亦隨之變化，只要周邊的多個刃角121能位於同一假想的圓形軌跡A即可；並且該旋轉幅度θ1可為10至15度之間的角度，該螺牙構造15的高度H1可為0.6至0.9mm，該牙山152的寬度H2可為0.4至0.7mm，該牙底153的寬度H3可為1.1至1.3mm，只要該牙山152與該牙底153寬度尺寸的比值為0.5即可，藉此使得本新型的螺牙構造15為較三角形齒更趨近方形齒的構造；該穿線構造14也可為僅於該穿線部13的後端面穿設一對穿線孔141而與一U形凹槽142相通的構造，或者該穿
線構造14也可以改設為於該錨釘本體11後端部周圍設有的開口，此開口與該旋刃插孔12相通，這時該旋刃20配合此開口於其周面形成一道延伸至前端露出該縫合錨釘10的直線溝槽，使縫線可由該開口穿入並由該直線溝槽的前端穿出，於該縫合錨釘10鎖入骨骼時縫線能絞合於該螺牙構造15與骨骼之間。
In addition to the aforementioned preferred embodiment of the present invention, the rotating
當前述較佳實施例使用時，如圖6所示，是以該旋刃20配合將該縫合錨釘10植入人體的骨骼B內；操作時該旋刃20的後端是附接於提供醫師手持的器械例如握把等手持裝置，接著醫師將該尖端部21對準敲入該骨骼B預定植入該縫合錨釘10處，接著轉動該旋刃20以其周圍的刀刃22在該骨骼B切削出圓形的導孔，同時帶動該縫合錨釘10同步轉動，以該螺牙構造15的入牙口151開始螺鎖入該旋刃20作為前導切削出的圓形導孔中，配合該入牙口151是以落後的方式接鄰於其中一刀刃22的設計，使得該螺牙構造15鑽入導孔的過程會更加順利，當該縫合錨釘10螺鎖至該骨骼B的預定深度後，抽出該旋刃20即完成植入該縫合錨釘10的操作。
When the aforementioned preferred embodiment is used, as shown in FIG. 6, the
本新型以截面積較圓形軌跡A小卻能挖出相同大小導孔的旋刃20驅動該縫合錨釘10，使該縫合錨釘10的旋刃插孔12能設計為較小的孔洞，能縮減該縫合錨釘10整體的設計體積，減少植入骨骼B時破壞周邊組織的程度。並且由於該旋刃20切削導孔同時該縫合錨釘10亦螺鎖入導孔內，使得醫師可省去預先鑿孔的麻煩，且該螺牙構造15由於是兩側之間的夾角θ2為50度的近似方形齒的構造，相較於三角形齒接觸骨骼B的面積更大，因此該縫合錨釘10植入固定時更加牢靠、穩固。
The present invention drives the
請參看圖7、圖8所示的本新型另一較佳實施例，是將該旋刃20的長度設為該縫合錨釘10兩倍的長度，該旋刃20後半部穿設於該縫合錨釘10的該旋刃插孔12並且前半部向前穿出該旋刃插孔12。

此本新型另一較佳實施例使用時，是執行一植入方法，如圖8所示，是將該縫合錨釘10留置於該旋刃20周圍的後半段，敲擊該旋刃20後端附接的器械例如握把，以該旋刃20的尖端部21直進的方式，利用該旋刃20的前半段於該骨骼B鑿出與該縫合錨釘10等長的鑿孔，接著向後至少抽回該旋刃20向前穿出該縫合錨釘10除尖端部21以外的部分，僅剩下該尖端部21露出該縫合錨釘10前端，再轉動該旋刃20帶動該縫合錨釘10旋轉，這時該螺牙構造15旋轉並以其前端的入牙口151由該旋刃20的其中一刀刃22所鑿出的鑿孔一角開始攻入該鑿孔，過程中該旋刃20僅負擔驅動該縫合錨釘10的作用而不用於挖孔，將該縫合錨釘10持續鑽入直至預定深度，最後將該旋刃20由該縫合錨釘10內完全抽出，即完成該縫合錨釘10的植入操作。
When another preferred embodiment of the present invention is used, an implantation method is performed. As shown in FIG. 8, the
本新型另一較佳實施例植入的方法，除了與前述較佳實施例所述同樣具有令醫師可省去預先鑿孔的麻煩，以及該螺牙構造15接觸骨骼B的面積大，因此該縫合錨釘10植入固定時更加牢靠、穩固的功效以外，由於該縫合錨釘10螺鎖入該骨骼B的過程中，該螺牙構造15是由截面積較小的鑿孔螺鎖入該骨骼B內，因此該縫合錨釘10植入該骨骼B過程當中所破壞的周邊組織更少，需要自行挖關鑿孔周圍的骨骼部分更多，令該縫合錨釘10植入骨骼B的固定構造更為緊密穩固，且手術後癒合的效果更佳。
The implantation method of another preferred embodiment of the present invention, in addition to the same as described in the foregoing preferred embodiment, allows the physician to save the trouble of pre-drilling, and the
